Which are the two best posters from U.S. presidential election campaigns (excluding ones for the primaries)?

My criteria: artfulness, effective messaging, and overall design.

Here are my selections:

1. Unknown Artist, Poster of Republican William McKinley, holding a U.S. flag and standing on a gold coin (symbolizing "sound money"), held up by group of men, in front of ships (for "commerce") and factories (for "civilization"), ca. 1896-1900. This beautiful color lithograph targeted both businessmen and laborers, as well as associating the candidate with both symbols of patriotism and fiscal soundness. In the background, the Sun rises, with its rays enhancing the positiveness of the message.

2. Rafael López, "Estamos Unidos" ("We are United"), Poster for Artists for Obama, 2012. This gorgeous poster features a layered oil painting, with the candidate gazing thoughtfully into the distance and shown from below (a common pose, which makes him seem more imposing), and a simple slogan and colors to appeal to Latino voters.

Of course, there are many other worthy designs. See 56 others by clicking here. What are your favorites? And which posters should be added?

In 2008, Rafael López created a powerful poster for the Barack Obama for President campaign. His poster, "Voz Unida" ("United Voice"), was one of ten posters designed for the campaign's Artists for Obama series. The 1000 prints of López's poster sold for $60 each. Some of the other artists in the series were Robert Indiana, Shepard Fairey, Scott Hansen, and Lou Stoval. The style of "Voz Unida"—showing a blue-tinted Obama surrounded by red, yellow, brown, and orange tones—was calculated to appeal to Latino voters, among others.

This year, López designed a new poster, "Estamos Unidos" ("We are United") (seen at the right). He was inspired to do so, he said, because of President Obama's support for "early education programs for children" and because he "has doubled Pell Grants so working families can afford college." Also, according to López, Obama's "bold actions to fix the broken immigration system and support of the Dream Act prove he is on our side." The poster is characterized by the same "visionary" gaze that was evident in the 2008 poster, with the same background colors.

The evolution of the painting of "Estamos Unidos" can be seen at López's Web site.
